These supermarkets in the Middle East bring a whole new meaning to the term home-grown produce. These stores actually grow their own produce on-site and just sell it at their hypermarkets. Not only does this sound like an environmentally better solution that cuts out supply chain emissions, but it would also help customers know exactly where their food came from. These little gardens use no soil, and some say they use up to 90% less water than normal greenhouses.
The only concern we would have is that the farmers were getting completely cut out of the process, but we're sure there could be a way to involve them in the growing.
